COMBINATION VALVE CONTROL.

Specification of Letters Patent.

Application filed April 16, 1917. Serial No. 162,308.

To all whom it may concern:

Beit knownthat I, HARRY Gr. BALTHASAR, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented certain new and use ful Improvements in Combination Valve Controls, of which the following is a specification.

This invention applies the principle of a combination lock such as used in safes, vaults, and the like to prevent the operation of internal combustion engines, and provides means therefor. It is intended especially to prevent theft, misappropriation, or misuse of motor vehicles and boats, aeroplanes, and the like.

In the accompanying drawings forming partV of this specification and in which like numbers of reference denote like parts Wherever they occur,

Figure 1 is a sectional view showing this device in relation to the instrument-board of a motor-vehicle of a particular type requiring the tilting from the vertical or horizontal of parts of the said device;

Fig. 2 is a front elevation of the combination dial and button for revolving the same, taken on the line 2 2 in Fig. 1;

Fig. 3 is a view looking at Fig. 1 in the direction indicated by the line 3 5 in Fig. 1, with the protective casing removed;

Fig. d is a detail of the connection between the combination dial on the instrumentboardand the operating shaft used in motorvehicles not requiring the device to be tilted as shown in Fig. l;

Fig. 5 is a detail of the index notches on the reverse side ofthe combination plate, taken on the line 5-5 in Figs. 1 and at; y

Fig. 6 is a detail ofa permutation tumbler in plan view; and y Fig. 7 is a top plan view of the permutation device and means actuated thereby for governing the valve.

Upon the instrument-board 1 or at an other convenient or suitable place is mounted the combination dial 2, which is revoluble in both directions alternatelyby means of the knob 3, as is common in such constructions when used in safes and the like.

Referring first to Fig. 4, a plate 4. is placed between the combination dial and the instrument-board l with a fiat spring 5 fastened thereto at 6, the said spring having a pointer 7 adapted to engage notches 8 and 9 on the inner side of dial 2, which notches are shown in Fig. 5. Notch 9 is of especial depth. Thus, when dial 2 is rotated, the operator will notice the entrance of pointer 7 into each of the notches 8 and will thereby be able to count the combination, but upon finishing the working of the combination will know'by the feeling that the pointer 7 has seated in the deeper notch 9. The combination being thus indicated to the operator by the feeling of pointer 7 riding over notches and the indication by the deeper notch- 9 of its having been completely worked keeps the secret of the combination, as it is impossible for any one sitting along side the operator to know what the combination is, as there is nothing visible on the exterior of the dial that will allow such observer to follow the working of the combination.

In the construction shown in Fig. l, the spring 10 is attached by` screw 11 to arm 12 of plate 13, and the pointer 14 on spring 10 operates through an opening 15 in arm 12 to engage notches 8 and 9 (as described in connection with Fig. l) on the reverse or inside of dial 2.

The face of dial 2 may, if desired, bear spaced marks which may coincide with the notches upon the reverse side shown in Fig. 5 or misleadingly placed not opposite the same, or the face of the said dial may be unmarked, inasmuch as the real working of the combination will not be by sight, but by the feeling of the pointer 7 (in Fig. Ll) or pointer 14: (in Fig. 1) riding into and out of the notches on the reverse side of dial 2.

Shaft 16 (the main part of which is not shown in the drawings) is a flexible shaft for operating the lock and valve, and shaft 17 is a non-flexible shaft for the same purpose in a different type of machine.

Referring to Fig. et, a bushing 18 having a collar 19 passes through the instrumentboard 1 and is screw-threaded at 2O to receive the screw-threaded cap 2l. having the collar 22. The bushing 18 and the cap 21 are kept from rotation by the set-screw 23. A pintle 24 having a flattened end 25 to cooperate with the flattened end 2G of shaft 16 is rotatable by knob 3, which simultaneously rotates dial 2, and collar 27 fastened to pintle certain parts when the butterfly valve 29 isY closed.

Valve 29 is mounted on rod 30 and adapted to rotate therewith, the said rod passing through a hole or bore 31 in plate 32, and one end of which red seats in socket 33 in the said plate 32, the said rod thus extending across hole 34 in plate 32.

Plate 32 is located between the carbureter 35 a nd the intake manifold BG in an internal combustion engine. The arrangement is the same if located at the exhaust manifold, as may be done. 1f located at the intake manifold the admission of gas from the carbureter is controlled by butteriy valve 29; if located at the exhaust manifold, the butterfiy valve 29 controls the exhaust of the products of combustion.

The valve 29 is opened by the rotation of rod 30, which is produced by pressure on the arm 37 by the lever 38, pivoted at 39 to the plate 40. The pressure of lever 38 on arm 37 is produced by the rotation of cam 41 by means of shaft 17 (or flexible shaft 16), the said cam 41 in its rotation (clockwise, as shown in the drawings) iinpinging upon lug 42 (or other suitable part) connected with lever 38. The lever 38 is rounded and beveled at its nose 43 in such manner as to slide easily on arm 37, which also is cooperatively shaped.

The cam 41 is fixed to rotate with shaft 17 (or shaft 16), while tuinblers 44 and 45 are loosely7 mounted in relation thereto. Pins 46 on the said cam 41 and tumblers 44 and 45 are adapted to engage with each other in such manner that when cam 41 is rotated clockwise the pin 46 depending therefrom will engage with the pin 4G projecting upwardly from tumbler 44, and the pin 4G depending from tumbler 44 will engage with the pin 4G projecting upwardly from tumbler 45. with the result that the said tumblers will be rotated. thereby removing slot 47 from alinement with lug 42. A partial rotation of cam 41 sul'lices to force lug 42 out of slot 4T, after which the pins 4G on cam 41 and tumbler 44 engage` whereupon the continued rotation of cam 41 causes the slot 47 in tumbler to become out of alinement withV lugV 42, and thereafter rotation of cam 41 in either direction causes slot 47 in tumbler 45 to be out of alinement with lug 42. `This movement consists in lirst forcing lug 42 out of slot 47 in both tumblers 44 and 45;

retaining the same by the periphery of cam 41 in such outwardly pressed position until slot 47 in tumbler 44 is moved out of alinement therewith, so that it will be held in its outwardly pressed positionby the periphery of tumbler 44 away from slot 47 therein; and then mixing up the combination by continued rotation or working it back and forth, which results in lug 42 being held out of slot 47 either by the high part of cam 41 or by the periphery away` from slot 4. of either tumbler 44 or 45 or both or of all threerof the said members. Y

A suitable 'spring' which inthe drawings is shownY as a coilspring 48 actuatesfboth the valve 29 and lever 38 bearinglug 42, so

that lug 42 will instantly drop into slot 47 as soon such slotin both tumblers 44and 45 and the low part of cam S41 are in alinement. This will occur whenever the combination. has been ,properly worked byv some one who knows it having made the requisite movements back and forth ofrknob 3 tolcause y engagement of=pins 46 in such mannerasfto set the tumblers 44 and 45v and cam 41. Itl is requisite that means be provided to make Y diiicult tampering. with the permutation tumblers. This provision need not attempt Y the qualities of a burglar-proof safe, but for the purposes necessary inlconnection with. locks used for the object herein contemplated it is enough the permutation tumblers be protected from ordinary interference, and in such manner thatthey cannot betalerv pered with without.considerable workand. dismantling ofthe machine, requiringcor? responding amount of workin replacement and installationof temporary expedients. As a rule, thefts of.motor-vehicles'orthe like are entirely frustrated unless accomplished quickly,

For the purposes just referred to, a protective cap 49 is provided, which, for pur-V noses of convenience, is attached by screw` 50 to plate 40, but which for real security is connected theretoand firmly held-between the carbureter and manifold 36 by bolts'V 51 that pass through holes 52 therein and holes 53 in a wing54of plate 40. ln some makes of machines, the said wing 54 may lie-- in the same plane as plate 40 and, in fact, be part of the same, but in a certain-type of motor-Vehicle the same must lie in a different plane, as shown in the drawings. The bolts 51 are the same bolts by which the carbureter PS5 and manifold 3G are attached together, and removal of the same to obtain access to the permutation..tumblers will necessarily take considerable time and yseriously Vdisarange the mechanism and require either its replacementor the installation of a temporary expedient between the carbureter and intake manifold.

The combination for any particular lock depends upon the positions of the pins 46 Lasarte v5V relative to each other on their respective members, and a plurality of holes `(not shown in the drawings) may be provided in the cam 41 and in each of the tumblers 44 and 45 allowing for the change ot' position therein relative to each other of the pins 46, so that when the combination ot any particular lock has been ascertained, as, tor instance, bya chauffeur, it can be easily changed by changing the pins 46.

Having thus described this invention, I hereby reserve the benefit of all changes in form, arrangement, order, or use of parts, as it is evident that many minor changes may be made therein Without departing from the spirit of this invention..
